All Along the Watchtower: Part 2

GTB-7VS - a 103mm thermobaric rocket propelled grenade used for anti-personnel and urban warfare. A thermobaric weapon is one that uses a special type of vaporized fuel that is dispersed in the air and then ignited via a vacuum pressure effect. This ignites the oxygen in the air and creates a high temperature (5,000 °C, 9,000 °F), high pressure shockwave that vaporizes any organic material in the blast zone and destroys electronic equipment. It is most effectively used in a contained area like inside a building or in close city streets. Thermobaric explosives are also used as a self-destruct/containment failsafe in buildings like the CDC where highly dangerous diseases are stored, in the event of a containment breach, or an attack on the building, detonation of a thermobaric device ensures every organic molecule and every piece of equipment in the building is destroyed to prevent an outbreak.
